DIATOR CONSTRUCTION.

Application filed February 17, 1928. Serial No. 819,612.

This invention relates to radiator construction and has special reference to a core or core units connecting the headers of the radiator and adapted for circulating a water or other liquid so that the water or liquid may be cooled, either by air passing between the units or through the units.

My invention, in its broadest aspect, involves as a new article of manufacture, a radiator cooling unit composed of inner and outer or concentric hollow members provided with heat disseminating members and one of these members of each unit is adapted to afford a sinuous or tortuous passage for water or other liquid so that the water or liquid may be cooled during its flow through such passage. The dissemination of heat is by conduction, either outwardly or inwardly relative to the water passage and in either instance a draft or blast of air increases the dissemination of the heat.

My invention further aims to provide cooling units that may be advantageously F used in condensers and such apparatus wherein a gaseous matter or fluids are to be condensed or converted into liquids.

My invention further aims to provide cooling units possessing strength and rigidity and when embodied in a radiator or a circulating system are adapted to provide a strong and durable structure which will withstand the vibrations and rough usage to which motor vehicle radiators are often subjected. The construction of such cooling 35 units precludes fractures and leakage and contributes to a radiator of pleasing design.

The above are a few of the features of my invention and others will appear as the nature of the invention is better understood with reference to the drawings, wherein- Figure 1 is a rear elevation of a portion of a radiator in accordance with my invention;

Fig. 2 is a vertical sectional view of the 45 same;

Fig. 3 is a similar view showing the radiator provided with oil lubricating units;

Fig. 4 is an enlarged horizontal sectional view of a portion of the radiator;

Fig. 5 is a perspective view of a portion of one of the cooling units;

Fig. 6 is a longitudinal sectional view of the same. and

Figs. 7 and 8 are views in cross section, of different forms of cooling units.

A radiator or condenser in accordance iii with my invention includes an upper header 1 and a lower header 2, said up er header having a filling connection 3 an an outlet connection 4, while the lower header 2 has an inlet connection 5 and is connected to the upper header 1 to permit of water or other liquid flowing from one header to the other. These headers, in the construction of a radiator, are supportedin or by a radiator frame 5 adapted to be suitably mounted on a. vehicle chassis or frame 7 partly illustrated in Figs. 1 and 4, and together with the radiator frame 6 forming no part of this invention other than contributing to a complete structure.

Connecting the upper and lower headers 1 and 2 and extending through a transverse 'member 8 of the radiator frame 6 are a plurality of cooling units, each comprising an outer tubular or hollow water conducting member 9 and an inner tubular or hollow air conducting member 10, the latter in the former and cooperating therewith in providing an annular water or liquid passage 11. The ends of the outer member 9 are soldered or otherwise connected to the bottom wall 12 of the upper header 1 and the top wall 13 of the lower header 2,. thus establishing communication between said headers. The air or fluid conducting member 10, has its lower end extending through the lower header 2 and soldered or otherwlse connected to the bottom wall 14 of the lower header in communication with the atmos-' phere, and the upper end of the inner member 10 is within the upper header 1 and bent at a right angle so as to be soldered or otherwise connected to the rear wall 15 of the upper header 1 in communication with'the at-- mosphere.

On the outer the headers 1 and 2, is a heat disseminating member or tin 16 and on the inner hollow member 10 is a heat disseminating member or fin 17, this member or fin being within the passage 11 and converting said straight.

passage into a. winding or sinuous passage. The heat disseminating members or fins 16 and'17 are spirally disposed on the members 9 and 10 and throughout the length of the outer member 9, each heat disseminating member or fin being made from a stri of metal having an edge thereof crimpe or corrugated, as at 18 so that the crimped or corrugated edge of the strip of metal may be spirally wound on the hollow member and hollow member 9, between too soldered or otherwise connected thereto. The member 17 may have its outer edges contactin with the inner wall of the outer member 9 thus placing the inner member 10 concentric of the axis of the outer member to form a double tubular unit possessing the requisite rigidity for a connecting member between the upper and lower headers.

Water or other liquid can flow through the passage 11 and be cooled by contacting with the Inner wall of the outer member 9, the outer wall of the inner member 10, and the member or fin 17 on the inner member 10. Heat is disseminated by conduction and with air flowing through the inner member 10 and impinging against the member or fin 16 the water can be expeditiously cooled.

As shown in Fig. 3 one or more of the inner hollow members 10 can be selected for cooling oil or other lubricants circulated through said inner members, in which instance, suitable connections 19 are made at the upper and lower ends of the inner members 10.

As shown in Fig. 7 the inner and outer members 10 and 9 respectively may be oval in cross section. In Fig. 8 a longitudinally corrugated heat disseminating member 21 is substituted for the spiral heat disseminating member 17, and unless necessary, I do not care to confine my invention to the cross sectional shape of a cooling unit or a heat disseminating member used in connection therewith. Such other changes as are permissible by the appended claim may be resorted to without departing from the scope of my invention.

' What I claim is:

A radiator comprising an upper header having a bottom Wall and a rear wall, a lower header having top, bottom and rear walls, outer water conducting members having the upper ends thereof connected to and; terminating at the bottom wall of the upper header and the lower ends thereof eonneetedl to and terminating at the upper wall of the' lower header, inner air conducting members extending through some of said outer members with the lower ends of said air conducting members connected to and terminating at the bottom wall of the lower header and the upper ends of said air conducting members being angularly formed within the up per header and connected to and terminating at the rear wall of said upper header, and heat disseminating members on said inner and outer conducting members between said headers.

In testimony whereof I affix my signature.
